Lens test: The Sony G Master Prime Set

The Sony G Master primes represent the brand’s flagship approach to optical precision and consistency. Built for full-frame coverage, our set includes the 14mm, 24mm, 35mm, 50mm, and 85mm lenses. Together they provide a complete and balanced focal range for both cinematic and commercial productions where accuracy, resolution, and reliability are key.

Design and Build

The G Master primes are designed with both still and motion production in mind. Each lens features a robust yet lightweight construction with precise manual control rings and smooth focus rotation (but sadly focus by wire). The lenses are compact and balance naturally with cameras such as the Sony FX3, FX6, and FX9, while maintaining a consistent feel across the entire lineup.

Optical Characteristics

The G Master primes are known for their neutrality. In our testing, they produced exceptionally sharp, high-contrast images with minimal distortion or chromatic aberration, even when shot wide open. The color reproduction is consistent across all focal lengths, with natural tones and accurate skin rendering. These are qualities that make them an excellent reference set in our lens comparisons.

At wider focal lengths, such as the 24mm, a small amount of geometric distortion can be observed, but it remains well-controlled. The lenses maintain edge-to-edge sharpness, particularly when stopped down slightly. The bokeh is clean and circular, thanks to Sony’s advanced 11-blade aperture design, contributing to a smooth, modern image character.

Performance

In practical use, the Sony G Master primes deliver exceptional performance across a wide range of shooting conditions. They maintain great sharpness and contrast at all apertures, with reliable aputure figures. Since we’re talking about auto-focus lenses, the focus tracking is smooth and precise, making them well-suited for handheld and gimbal shooting. The lenses have controlled chromatic aberration and the minimal distortion ensure consistent image quality across the frame.

Final thoughts

The Sony G Master primes form a precise, modern lens set that prioritizes optical consistency and sharpness without frills. They are a dependable choice for productions requiring a neutral look that can be easily shaped in post-production. Whether used on their own or as a benchmark against more character-driven lenses, the Grand Masters represent a reliable foundation for professional cinematography.
